Pure solid solutions \(\mathrm{Ca}_{3} \mathrm{Sn}_{2+x} \mathrm{Si}(\mathrm{Ge})_{1-x} \mathrm{Ga}_{2} \mathrm{O}_{12}\) with the garnet structure have been evidenced in the composition range \(0 \leq x \leq 0.95\). This implies that a part of the \(\mathrm{Sn}^{4+}\) cations (equal to \(x\) ) is l
